Transform Cache Constraint 变换缓存约束

转换缓存约束 用于串流来自 Alembic 的在变换矩阵制作的动画(例如刚体或摄像机运动)。

当 导入Alembic文件 时，变换缓存约束会自动添加到具有动画变换的物体中。对于时变网格(变形动画之类)，将使用: 网格缓存序列修改器。

选项

Transform Cache Constraint.

Cache File 缓存文件

要选择的Alembic 文件的数据块菜单。

File Path 文件路径

Path to Alembic file.

Sequence

缓存是否在一系列文件中分离。

Override Frame 重写帧

是否要使用自定义帧用于查找在缓存文件中的数据，而不是使用当前的场景帧。

The Frame value is the time to use for looking up the data in the cache file, or to determine which to use in a file sequence.

Frame Offset

Subtracted from the current frame to use for looking up the data in the cache file, or to determine which file to use in a file sequence.

Manual Scale

遵从世界原点放大或缩小物体值。

Velocity Attribute

The name of the Alembic attribute used for generating motion blur data; by default, this is .velocities which is standard for most Alembic files.

Velocity Unit

Defines how the velocity vectors are interpreted with regard to time.

• Frame

  The velocity unit was encoded in frames and does not need to be scaled by scene FPS.

  Second

  The velocity unit was encoded in seconds and needs to be scaled by the scene FPS (1 / FPS).

Object Path物体路径

在档案的Alembic 物体的路径.

Influence

Controls the percentage of affect the constraint has on the object. See common constraint properties for more information.
